Removing the composer draft let me delete the page type, however it would be nice to actually know what pages are using the type instead of a cat and mouse game of deleting the trash, clearing the cache, or going through endless pages to see if they are for some reason using a page type.

I also had to go to each page and in versions select "old versions" and delete. Now that I'm checking some other pages I see I have a lot of junk in there. I ran the automated job a dozen times but still have pages of old versions on some pages.
